Extract

A crucial factor in the prevention of hypothermia in the neonatal lamb is the functional activitation of a mitochondrial uncoupling protein (UCP1) in brown adipose tissue. UCP1 disappears from lamb brown fat over the first 14 days of life (Finn et al., 1998), but it is not known whether this process can be modulated in lambs by the release of catecholamines which have been established in rodents as a mediator of the response to cold stress. This study examines the effect of administering a β-adrenoceptor agonist on the disappearance of UCP1 and UCP1 mRNA during early neonatal life, using immunohistochemistry and in situ hybridization.
